Common ceilings include light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long strip aluminum gusset ceiling, square painted aluminum gusset ceiling, stained glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, whole room duplex ceiling, etc.

[0003] The ceiling occupies a very important position in the entire interior decoration. Proper decoration of the ceiling of the room can not only beautify the indoor environment, but also create a colorful indoor space artistic image. When choosing ceiling decoration materials and design schemes, we must follow the principles of saving materials, firmness, safety, beauty and practicality.

[0004] Traditional suspended ceilings usually consist of three major parts: hangers, keel frames and cover panels. With the development of architectural design, light steel keel suspended ceiling installation is currently a common method of suspended ceiling installation. It is fixedly connected to the ceiling through hangers. The upper part of the keel frame is connected to the hangers, and the lower part is often connected to the cover panel or other accessories through hangers or auxiliary keels with self-tapping screws. The ceiling base plate is installed and fixed on the ceiling keel. Although the appearance of this type of ceiling is relatively flat and uniform, in actual use, since the height of the ceiling cannot be adjusted, it is only suitable for simple flat integral ceilings. During the installation process, it is difficult to adjust the angle, has high requirements for flatness, and is very dependent on the flatness of the base layer, making it difficult to meet some specific decorative design requirements.

[0028] In the existing interior decoration, the ceiling is an important part of the interior decoration. Those skilled in the art should know that the ceiling usually refers to a kind of decoration on the top of the house living environment, which generally refers to the decoration of the ceiling. The existing common ceilings include light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long strip aluminum gusset ceiling, square painted aluminum gusset ceiling, stained glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, whole room duplex ceiling and many other types of ceilings.

[0029] Traditional suspended ceilings usually consist of three major parts: hangers, keel frames and cover panels. With the development of architectural design, light steel keel suspended ceiling installation is currently a common method of suspended ceiling installation. It is fixedly connected to the ceiling through hangers. The upper part of the keel frame is connected to the hangers, and the lower part is often connected to the cover panel or other accessories through hangers or auxiliary keels with self-tapping screws. The ceiling base plate is installed and fixed on the ceiling keel. Although the appearance of this type of ceiling is relatively flat and uniform, in actual use, since the height of the ceiling cannot be adjusted, it is only suitable for simple flat integral ceilings. During the installation process, it is difficult to adjust the angle, has high requirements for flatness, and is very dependent on the flatness of the base layer, making it difficult to meet some specific decorative design requirements.
